Holy Spirit Cathedral was built in Baroque style between 1633-1642 as the main temple of Catholic Bernadine convent. During the 1700-1800s it was reconstructed to the present architectural shape. In 1852 the convent was closed, and its nuns were sent to Nesvizh town. In I860 the former monastic church was turned into the orthodox church. After ten years an orthodox monastery was opened here.
In 1918, after the closing of the monastery, the building was used for various purposes: as a sports hall, a transit prison for the dispossessed peasants. The services were renewed during World War II, in 1943. The most valuable relic is the wonder-working icon of Mother of God found in 1500. The other relic of the temple is imperishable relics of St. Sofia of Slutsk, a grand daughter of Anastasia of Sluck.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
